Have had my new truck for 2.5 months and have 4800 miles on it. I use it for work and tow a 21 foot toy hauler loaded that weighs roughly 9000lbs total. Have 6 spd manual and it works particularly well since I drive over the high sierra mostly. Fuel mileage on my most recent long trip (3000 miles) averaged 10.5 for the duration. That was through Northern Nevada, Colorado, New Mexico and Arizona. Worked great love the power. Yesterday hauled firewood with a 7000lb dump trailer in snow and decomposed granite. Use low range which shifted in beautifully and having the exhaust brake is a big plus. I enjoy driving the truk itself really like Uconnect and the general feel.
exhaust brake, built in sattelite radio, manual shift and of course the Cummins
built in brake controller should come standard with running boards.
